Some idea's are so cool I'm just jealous I didn't think of them myself. With all the crappy, time consuming and totally useless social network sites (linkedin being the exception) it's refreshing to see something like slideshare.com.
The idea is pretty simple - share your slides ! In fact, now that I think of it - it's basically like youtube - but with slides - or presentations.
Just create an account - upload your presentations and slideshare will convert your pdf's or ppt's or whatever format into a flash driven presentation. Which at that point, you'll be able to embed them into your website.
Just for fun I uploaded the presentations I did for UKOUG2007 and UKOUG2008. The 2007 one got selected by the slideshare editorial team as a showcase on their technology page. Way cool!
Your presentation Extending the Oracle SSO is currently being showcased on the 'Technology' page by our editorial team.
It's likely to be there for the next 16-20 hours...
Cheers,
- the SlideShare team
I'm pretty sure their editorial team is a couple of uber-geeks as the selected presentation 'Extending the Oracle Single-Sign-On server' is … well … kind of geeky … and I even dumb'ed it down a bit. It's all about PKI, certificates, authentication, reverse proxies, apache and … fitting Oracle's SSO server somewhere in between
It's also loaded with PowerPoint's custom animations, so you actually need to download it and run it in PowerPoint to get an idea of what I'm aiming for … so the editorial team must have been geeky enough to download it and let all the animations spin their heads around.
The content itself is based on the work I've been doing at a customer's site - an insurance company - that had very specific requirements regarding their SSO architecture. They had made Oracle their choice of platform as they had been using the Oracle RDBMS for about 10years (I was the one who set it up back then). So it was only natural that when they wanted to 'web-enable' their back-office applications, and give their - and third party - brokers access to some of their back-office applications, they chose Oracle's Internet Application Server.
As all their business logic was built within PLSQL - the fat database model or database centric approach as Toon Koppelaars calls it - it was quite easy to develop a web front-end for it. The thing that they struggled the most with, was integrating Oracle single sign on with their fancy and expensive vpn/ssl boxes. Not only that but, they needed to integrate Oracle SSO with a federated authentication infrastructure, so that third party brokers, who were already authenticated through a third party identity provider could automatically logon to their applications, mapping third party identities to their identities.
And we're only halfway there - they also wanted to run their own certificate authority (thank god for Oracle CA … are we the only one actually using it in production ? ). Using their own CA they wanted to generate client certificates so that internet brokers could authenticate themselves with their own client certificate. But they also had the choice of using their Belgian passport to authenticate themselves against Oracle SSO. And because the insurance holding has multiple companies, the logon screens needed multiple look-and-feels … oh and multi-language support of course.
So for the last couple of years I have been busy pulling Oracle's SSO server inside-out, integrating it with a juniper 4000 VPN/SSL series - which we threw out in favor of an apache2 based SSL terminator and reverse proxy. The juniper box was just holding us back. I did have to write some custom apache filters for Oracle Portal. I think Oracle Portal generates some of the weirdest html I've ever seen… and mod_proxy_html wasn't up to the job for that
I've also integrated SAMLv2 with Oracle SSO. I had to write a java based SAML proxy to get it done, because the SAML token needed to be transferred over a HTTPs connection using a client certificate authentication - but it works like a charm. This was only done this year - so it's only slightly mentioned in the presentation. We had a kind of DIY federated authentication before that, as the third party was not finished implementing a SAML IP themselves.
So I wrote various software packages that tied it all together, like :
Anyway - that's in a nutshell what the presentation is about. Never mind all the DBA stuff and java programming … working with these technologies was awesome … and it'll help me a grea lot in my DUDE work when I finally finish support for unloading data encrypted using Transparent Data Encryption (TDE)
Oh - here's the presentation embedded ... but you'll need to download it and run it powerpoint to get the animations running !
